Translocation Down syndrome is the only form of the disorder that can be passed from parent to child. However, only about 4 percent of children with Down syndrome have translocation. And only about half of these cases are inherited from one of the parents.
How Down syndrome affects Kids
Kids with Down syndrome tend to share certain physical features such as a flat facial profile, an upward slant to the eyes, small ears, and a protruding tongue.
Low muscle tone (called hypotonia) is also characteristic of children with DS, and babies in particular may seem especially "floppy." Though this can and often does improve over time, most children with DS typically reach developmental milestones — like sitting up, crawling, and walking — later than other kids.
At birth, kids with DS are usually of average size, but they tend to grow at a slower rate and remain smaller than their peers. For infants, low muscle tone may contribute to sucking and feeding problems, as well as constipation and other digestive issues. Toddlers and older kids may have delays in speech and self-care skills like feeding, dressing, and toilet teaching.
Down syndrome affects kids' ability to learn in different ways, but most have mild to moderate intellectual impairment. Kids with DS can and do learn, and are capable of developing skills throughout their lives. They simply reach goals at a different pace — which is why it's important not to compare a child with DS against typically developing siblings

who are diagnosed with Down syndrome. There are more than 250,000 people living in the United States with a Down syndrome diagnosis (Genetics). Down syndrome is not a hidden disability rather it has physical attributes that can make the diagnosis obvious. Furthermore, individuals with Down syndrome and their families have to cope with multiple health issues, cognitive limitations, and the stigma of having a disability. In order to understand the struggle that people with Down syndrome must face from…

Down syndrome
Down syndrome takes its name from Dr. Langdon Down. He was the first person to describe the syndrome in 1866. The earliest recorded incident of someone having Down syndrome dates back to an altar piece painted in a church in Aachen, Germany in 1504. Although the syndrome is named after Dr Langdon Down, he did not understand the condition, as we know it today. The syndrome was referred to as having mongolism. This was because people who have Down syndrome have similar physical characteristics…

Looking down the hole that led to nowhere, I could taste the bitterness of my fate; the sour spit that hunger had released into my dry mouth drizzled around in an uncontrolled manner. My stomach churned and my intestines were strangled, as though a snake had twirled around them and slit them with its sharp and jagged teeth releasing a strong poison that irritated the surface of my innards.
My eyes blurred for what seemed eternity leading me to the subconscious of my mind.
Every worry and…

Never Back Down Review
A) Event Synopsis and Theme
1. The film opens in the middle of a high-school football game, with Jake Tyler helping his team to win. Frustrated, one of the players from the opposing team taunts him about the death of his father from drunk driving. Known for his hot temper, Jake immediately begins a brawl with the opposing player. The brawl is captured on the crowd's mobile phones and personal video cameras, and soon is downloaded to the internet.
This is in fact the last game…

Facts on Down Syndrome
*Down syndrome is not a lethal anomaly. One to two percent of persons
born with this disorder have uncorrectable heart defects at birth. The average
life expectancy for all others is now beyond age 55 years.
*Today less than 5% of persons with Down syndrome have severe-to-
profound mental retardation. The majority are on the border of mild-to-moderate
mental retardation…

Abstract
Down syndrome is an inherited disorder caused when abnormal cell division occurs the outcome is an extra genetic material from chromosome 21. Having an extra chromosome affects the physical appearance of an individual and also causes health issues and delayed development. With Down syndrome being the most common genetic chromosomal disorder and cause of learning disabilities in children, we like to see how the student would interact in a school setting. How would a student with Down syndrome…

Down Syndrome in Children
Down syndrome is one of the most common and easily recognized genetic disorders. It is caused by abnormal cell division that involves the 21st chromosome pair of the 23 pairs of chromosome found in all normal human cells. There are three types of these abnormalities, which are non-disjunction, translocation, and mosaicism. Ninety five percent of children born with Down syndrome are a non-disjunction type which is three rather than two chromosome 21s. About three to…

Having a Down syndrome is such a difficult situation for an individual to have. They have slow physical and mental capabilities that lead them to discrimination. Physical features of having a Down syndrome. Including flattening of the head; slanting of the eyelids; a gap between the first and the second toes; a depressed nasal bridge; relatively small ears, mouth, hands and feet; short stature; decreased muscle tone and loose ligaments among others. Not every child with Down syndrome has all…

genetic or congenital defect or disease. One of the most common of these genetic disorders is Down syndrome. This disorder takes its name from Dr. Langdon Down, who was the first to describe it formally, in 1866.
Down syndrome is a condition marked by abnormal physical and mental development that is caused by a genetic defect. This genetic defect is caused by an extra chromosome. People born with Down syndrome have 47 chromosomes compared to the normal amount of 46, 23 chromosomes inherited from…

Down syndrome has three different types of occurrence, Trisomy 21, Translocation, and Mosaicism. Trisomy 21 is the most common one and it accounts for 95% of all cases. It is a congenital disorder which consists of having a whole extra chromosome in the 21st pair of chromosomes in every cell of the body; the person ends up having 47 chromosomes instead of the usual 46. Down syndrome was named after Dr. John Langdon Down, an English Physician, who, in 1866, was the first ever to describe the characteristic…
